Fig. 1 is the autonomous power supply system structural representation that utilizes the various energy resources complemental power-generation.
Embodiment:
Below in conjunction with accompanying drawing the present invention is specifically described:
Fig. 1 is the autonomous power supply system structural representation that utilizes the various energy resources complemental power-generation, and as shown in the figure, wind-driven generator is connected with controller by rectified three-phase circuit, and photovoltaic battery panel directly is connected with controller; The electric energy that wind-driven generator sends with photovoltaic battery panel after by the rectified three-phase circuit rectification is sent in the controller; Comprise charge-discharge control circuit, current rectifying and wave filtering circuit, photovoltaic battery panel automatic tracking control circuit, temperature detection protective circuit and system voltage in the controller and detect protective circuit; Charge-discharge control circuit links to each other with storage battery.The photovoltaic battery panel automatic tracking control circuit links to each other with stepping motor on the photovoltaic cell board mount, temperature detection protective circuit and system voltage detect protective circuit respectively with system either power generator, photovoltaic battery panel and controller on the temperature sensor laid link to each other with voltage sensor.Temperature detection protective circuit and system voltage detect protective circuit can real-time detecting system; realize the real-time switching of multiple operating state; satisfy user's power demands; simultaneously; detected temperature and information of voltage are analyzed by controller; realize the effect of the operating state of monitoring system, when system goes wrong, can in time respond, avoid bigger loss.Controller is connected with the switch of diesel engine generator, is used for starting and closing diesel engine generator work.Controller links to each other with inverter circuit, by inverter circuit direct current is transformed into alternating current and uses for user load.Controller links to each other with off-load resistance.Diesel engine generator also links to each other with user load, can directly supply with user load.
Photovoltaic battery panel and wind-driven generator are the regenerative resource harvester, can be electric energy with wind energy and conversion of solar energy respectively.Storage battery can adopt lead acid accumulator or lithium battery, is used for storing the unnecessary electric energy that electric energy that electricity generation system is sent is not used by the user as yet.Off-load resistance is power resistor, chooses power resistor according to electricity generation system maximum generation high power value.Diesel engine generator produces electric energy by burning diesel oil, when regenerative resource can't produce electric weight in electric energy and the storage battery and exhausts, can start diesel engine generator directly to user's power supply, thereby guarantee the reliability of user's power supply.Because diesel engine generator only under extreme conditions uses, so the environmental pollution degree that diesel engine generator produced is very little, can ignore.In addition, because diesel engine generator makes this system improve greatly the reliability of user's power supply as the existence of emergency power supply in the system.
Rectified three-phase circuit is rectified into direct current with the three-phase alternating current that wind-driven generator sends, and the current rectifying and wave filtering circuit that the direct current that sends with solar-energy photo-voltaic cell is sent in the controller carries out current-modulation.If user's this moment needs electric energy to supply with; then can direct current be transformed into alternating current by inverter circuit uses for user load; if the user does not need electric energy to supply with this moment; then direct current energy can be got up by charge-discharge control circuit input battery stores; if charge-discharge control circuit detected storage battery and was full of this moment; then the direct current that is produced will discharge by off-load resistance, and the protection storage battery did not lose efficacy because overcharge, and had prolonged the useful life of storage battery.
Because the spatial and temporal distributions of wind energy and solar energy is inhomogeneous, having a kind of regenerative resource in system's use can't be by the normal situation of utilizing generating, this moment, controller can detect the power supply unit that can't generate electricity in the system, and by control circuit this equipment and system are isolated, system utilizes another renewable energy power generation.When only utilizing a kind of renewable energy power generation or solar energy and wind energy all can't be utilized normally to send electric energy, storage battery will discharge the electric energy that stores in the storage battery by charge-discharge control circuit and convert the use of alternating current supply user load to by inverter circuit, after if electricity of accumulator has also discharged, then controller starts diesel engine generator directly to user's power supply, thereby guarantees the reliability of user's power supply.Photovoltaic battery panel automatic tracking control circuit in the controller can detect the altitude of the sun angle information by photo-sensitive cell, and according to the angle of sun altitude by the stepping motor adjustment photovoltaic battery panel on the control photovoltaic cell board mount, the photovoltaic energy conversion rate that guarantees photovoltaic battery panel is a maximum, improves the efficient of system.
